FIGURE 1.1 shows the substructure of a structure - NSC Civil Technology Woodworking - Question 1 - 2017 - Paper 1

The minimum measurement of the foundation bottom below ground at 1.1.B is 150 mm.

The thickness of the wall construction in FIGURE 1.1 is 220 mm.

The floor at 1.1.C is manufactured from concrete.

Part 1.1.D is called hard core filling.

1. Solid base for concrete floor.
2. Provides a level surface.

Determining the water table level is crucial because:

1. It can affect the stability of the foundation as high water levels can weaken sub-soil, leading to sinking.
2. Water accumulation can cause dampness and structural damage.

Holes in clay bricks are advantageous because they:

1. Allow for even heat distribution during baking, leading to thorough curing.
2. Reduce the risk of cracking by allowing steam to escape.

Three properties of face bricks are:

1. They are hard and durable.
2. They have high strength.
3. They do not absorb water easily.

The manufacturing process of clay bricks involves the following steps:

1. Clay is excavated and mixed with water to achieve the desired consistency.
2. The mixture is shaped into blocks using molds.
3. The shaped bricks are dried in the sun.
4. Finally, they are baked in kilns to harden them.
